EN The paper presents a method to determine the displacement of the active element in the giant magnetostrictive transducer. In the proposed model the coupling of magnetic and mechanical field has been taken into account. To determine the distribution of the magnetic and the mechanical fields the finite element method was used. Characteristics of the displacement of the active element in the transducer as a function of the supply current were calculated and measured. The obtained results of simulations and their comparison with the measurements show that the applied method is sufficiently accurate.
